My very short 6th grade story Shoelaces, won me the right to spend my Saturday morning in the public library, along with the several other student winners, autographing copies of our stories for our eager public.

For a long time I had a chemistry lab in the basement
(and I only injured myself once).

In 8th grade, I was the centerfold of the ICCSD Newsletter: An Information Publication for Residents of Iowa City Community School District (Volume 3, Number 2; December 1980).

Home automation

I started a Closed Caption decoder card for Apple IIgs (project stalled; "stone knives and bearskins" version works on breadboard)

Interesting stuff I bought:

(March 2002) ActiveWire-USB from AcitveWire, Inc. Interface USB to anything (16 bits of digital I/O).
So far I have no specific plans for it, and have only proven that I can blink colored LEDs. Maybe I'll try to talk to the SAA5252 closed-caption
chip that I was playing with a few years ago.

Caller ID to Serial kit from ITU Technologies (formerly itutech.com...they seem to be
out of business these days). I use mine
to display caller ID on a message board.

A Macintosh XClaim TV tuner box from ATI lets me get closed captions into Mac-readable form.
I wrote some software to process the text further, in real time, to provide reasonable capitalization
and better line breaks. I wish ATI would provide some documentation on how to get the rest of the
data that's embedded in the video signal (Extended Data Service), but I have struck out.

I bought a house in June, 1999 and have added phone jacks and
Cat 5 network jacks both upstairs and downstairs.
Home Tech's web pages and staff were very helpful. I had
to crawl under the house as well as in the attic, open up drywall, and buy a 16"-long drill bit.
I didn't do a detailed write-up, but Andy McFadden wrote about his wiring project.

Nifty List, Davex, and DIcEd used to be Shareware. They are now freeware, and someday
I'll package these up and donate them to the Lost Classics project. (If you care, remind me.)

February and March 2002: I helped Rich Dreher with the firmware & software for his
CFFA board: Compact Flash for Apple II.
— The firmware presents the storage to the Apple II as one or more block devices, using the ProDOS
and SmartPort conventions.

2006: I wrote most of the firmware for Rich Dreher's
CFFA1
board for the Apple 1 and replicas. — This was a different sort of project. Instead of presenting
the storage to a host operating system as a block device, it's a menu system (and small API) that implements
simple file operations on ProDOS-formatted volumes. It supports a single level of subdirectories and reads/writes
entire files at a time.
